Abstract: Abstract: 【Objective】The purpose of this study was to evaluate the degree of ecological security of the county forest ecosystem in Hunan Province, and to provide evidence-based recommendations for the establishment of an ecological protection policy. 【Method】This study was undertaken for 122 counties of Hunan Province, based on data from the years 2000, 2005, 2010 and 2015. Combined with fuzzy matter-element method and spatial correlation analysis, this study analyzed the forest ecological security using ArcGIS and GeoDA software. 【Result】Spatially, the areas with the highest value of forest ecological security index were generally distributed in the northwest and southeast of Hunan, while the areas with the lowest value were located in the Dongting Lake Plain. Hunan forest ecological security was not optimistic overall due to the higher energy consumption. Temporally, 97.54% of the counties showed a clear downward trend. Spatial correlation analysis showed that the counties of Hunan Province showed significant agglomeration, the high-high agglomeration districts were generally distributed in the south and east of Hunan, and the low-low agglomeration areas were mainly distributed in the northern districts. 【Conclusion】On the basis of the above spatial distribution structure, the following recommendations can be adopted by the local governments: The industries with high pollution and high energy consumption should be strictly limited to the high-high agglomeration district. The restoration of forest vegetation should be strengthened in the low-low agglomeration counties. Forest protection and nature reserve construction should be actively carried out in the low-high agglomeration counties, while forest products processing industries can be developed according to local conditions in the high-low agglomeration counties.
